The frame B is also enlarged centrally, and is provided at such enlarged portion with a chamber forming a hydraulic cylinder H. This cylinder is preferably provided with a removable lining H and carries the hydraulic plunger F 2, to which the riveting-die F5 is secured. lVater under pressure admitted behind this plunger forces it outwardly, and the die thereon coming in contact with the hot rivet upsets the end thereof in the usual manner.

The plunger F2 is provided with a cylinder F5, also lined, as at d2, for the reception of the piston I, fast on the end of the hollow stem I'. This rod is provided with openings c2, communicating with the central passageway c3, for the admission of water into the cylinder F3. Stem I is provided at d2 with a shoulder, which bears against the lining` in cylinder ll, while the outer end thereof is threaded for the reception of the nut d3, which latter locks the stem and the piston or plunger thereon solidly in place. The rear end of cylinder F3 is closed by the nut J, which latter is open centrally to receive the stem l.

Frein the foregoing it will be seen that by opening cylinder F3 for the escape of water therein and admitting water behind plunger F2 the latter, with the die F5 thereon, is moved outwardly, thus upsetting the rivet. By now permitting the water behind plunger F'2 to escape and admitting water under pressure to cylinder F3, between the nut J and the plunger or piston I, the plunger F2 is moved rearwardly into its cylinder.

The frames A and B are practically alike, each carrying two magnets and each a tool. Each is designed to be supported on its trunnion d independent of the other and can be raised or lowered to bring the holding-die and riveting-dic in alinement with the rivet, and when so placed on opposite sides of plates the magnets of one frame rest opposite the magnets of the other frame, and when energized each operates to attract the other, and hence both are held firmly in position.

The form of riveter just described is designed particularly for riveting joints between plates, as in the plates forming the partitions between compartments of a metal boat or prison, while the riveter to be now described is designed more particularly for riveting the ends and edges of the plates to the angle-irons at the sides, top, and bottom of the compartment. In this construction, which is disclosed in Fig. 2, each frame K and K carries a single electromagnet K2 somewhat larger in proportion than the mag nets of the frames A. and B. Mounted on frame K' is the lever K5, provided at one end with the holding-die 7a4 and at the other end with the movable stem and cam, the latter being constructed as in Fig. l. The stem, however, instead of carrying the holdingdie, as in Fig. l, carries the yoke K4, which latter is adapted to bear against the plate and securely hold the holding-die in contact with the head of the rivet. Lever K7 is mounted on frame K and is provided at one end with a riveting-die 7c and at its opposite end with plunger k7. This plunger moves in cylinder 7c3, integral with yoke K5, which latter is located diametrically opposite yoke K4, so that when the riveter is .upsetting a rivet the pressure on both sides of the plate is equalized and damage to the plate prevented. The construction of the cylinder and plunger is identical with the corresponding parts of Fig. l, except that in the construction shown in Fig. 2 the cylinders, plungers, and stem are formed in the arc of a circle concentric with the axis of the lever K7, so as to permit the yoke K5 to rest solidly and iiatly on the plate while the lever K7, carrying the riveting-die, is making its full stroke.

The principal difference between the construction just described and that shown in Fig. lis that in Fig. l the cylinders, plungers, and dies are located centrally between the ends of the frame, whereas in the construction disclosed in Fig. 2 the holding devices and dies are located at the ends of the appa- .ratus and are carried by levers mounted on the main frame.

In the construction in Figs. 3, 4.-, and 5 I have disclosed devices for supporting the riveter, the supportin devices carrying the mag nets and the riveting devices movable thereon, so that the riveting devices can be moved from one rivet to another throughout the lengths of the frames without moving the frames or denergizing the magnets.

L represents the frames, each of which is provided at its ends with magnets L', preferably oblong in shape, as shown in Figs. 4 and 5. These electromagnets are like those shown in Fig. 1, and when energized and placed against a metal plate hold the frames solidly in position. Each frame consists, essentially, of two sides and ends, and is open at its front and rear for the passage of the carriers L2. Each carrier is provided, preferably, with eight wheels, four to a side, the four wheels Z at one end thereof resting against the fiat edges l of the sides of the frames, and the four wheels near the opposite end resting against the fiat edges Z/ of the opposite sides of the frames. Centrally mounted in each frame and running approximately the length thereof is a screw L3, the lower end of which terminates beyond one end of the frame, for the attachment of a hand-wheel, lever, or wrench. This screw passes through the car IOO IOS

riers L2, the latter having a screw-threaded way for the passage of the screw. Hence by turning the screws the carriers can be moved toward either end of the frames.

Suitably jonrnaled to each carrier L2 is a frame M, one of which is provided with the cylinder M', carrying the riveting-plunger and die M2, while the other frame M is provid ed with the cylinder M5, carrying the holding-plunger and die M4, the cam M7 by which the holding-plunger and die are moved toward the rivet, and spring (not shown) for moving the die away from the rivet.

Each frame is provided on its end opposite its cylinder with a weight for counterbalancing the weight of cylinder, and each is also provided with a worm-wheel M4, located concentrically with the axis of the frame; These worm-wheels are each engaged by a wormshaft M5,`mounted in a bracket M6, depending from its respective frame A.

By turning the worm-shaft it will be seen that the frames carrying the riveting and holding tools can be turned to the positions shown in Figs. 4 and 5. As shown in Fig. 5, a line of rivets can be riveted without disturbing the frames L, and as shown in Fig. 4t after riveting the plates to the. angle-iron the riveter can be turned to the overlapping edges of the plates without disturbing the frames.

This device is particularly applicable for rivet-ing together the plates and angle-irons from which the compartments of the modern vessel are now constructed, and besides lessening the cost of such work is much more rapid and effectual than the ordinary handriveting which has universally been employed on work of this kind.

IVhile I have described the improvements as applied to a riveter, it is evident that they can be employed with other metal-working tools, such as drills. Hence I would have it understood that I do not confine myself to the details of construction of the parts nor to the uses of same herein referred to, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.
